a Schematic illustration to show light-phase exfoliation to prepare TiH1.924 nanodots. b A photograph of commercial TiH1.924 powder, the TEM images and corresponding photographs of exfoliated dispersions using various solvents (H2O, glycerol, dimethyl sulfoxide/N-methyl pyrrolidone (DMSO/NMP) DMSO/NMP, DMSO, polyethylene glycol 200 (PEG 200), NMP, N,N-dimethylformamide (DMF)/NMP, pyridine, DMF, acetonitrile, tetrahydrofuran (THF), ethanol, and acetone) for TiH1.924 exfoliation. c The surface energies of various solvents used to exfoliate TiH1.924. d A photograph of exfoliated TiH1.924 nanodots in NMP. Inset is the particle-size distribution (PSD) of TiH1.924 nanodots determined by the TEM image (n = 100 nanodots examined over TEM images). e High-resolution TEM (HRTEM) image of TiH1.924 nanodots. f XRD spectra of TiH1.924 nanodots. g XPS spectra to show Ti 2p peaks for the TiH1.924 nanodots sample. h TEM images and PSD of ZrH2 nanodots, CaH2 nanodots, and HfH1.983 nanoparticles exfoliated in NMP (n = 100 nanomaterials examined over TEM images). A representative image of three biological replicates from each group is shown in b, e.
